Compiler Error C2390

'identifier' : incorrect storage class 'specifier'

The storage class was not legal for the specified identifier with global scope.

The default storage class for this context was used in place of the illegal class.

Correct use of storage classes includes:

• If the identifier is a function, declaring it with extern storage.
  
  
• If the identifier is a formal parameter or local variable, declaring it with auto storage.
  
  
• If the identifier is a global variable, declaring it with no storage class (that is, auto storage).

The following is an example of this error:

register int i;        //error
void main ()
{
   register int j;     //OK
}
